VARIETAL DENOMINATION

cv. ‘Sunbapive’

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of petunia plant originated from the crossing a seedling called ‘Fantasy Crystal Red’ (♂) and a wild type Petunia plant called ‘1792’ (♀).

The Petunia is a very popular plant that is used for flower bedding and potting in the summer season. There are only a few Petunia varieties which do not have an upright growth habit and which have a high resistance to rain, heat, and diseases. The Petunia plants of the ‘Revolution’ series include ‘Revolution Purple pink’ (U.S. Plant Pat. No. 6,915), ‘Revolution Brilliant pink’ (U.S. Plant Pat. No. 6,914), ‘Revolution Brilliant pink-mini’ (U.S. Plant Pat. No. 6,899), and ‘Revolution Blue vein’ (U.S. Plant Pat. No. 9,322). These are decumbent type plants having long stems, a lower plant height, abundant branching, and a high resistance to heat, rain and disease. However, there are only a few Petunia varieties having a great profusion of flowers, vivid colored and vein patterned flower petals and a high resistance to rain, heat, and diseases. Accordingly, this invention was aimed at obtaining a new variety having vivid purple pink colored petals with vivid reddish purple vein together with the above features.

The new variety of petunia plant according to this invention originated from crossing a seedling called ‘Fantasy Crystal Red’ (♂) and a wild type Petunia plant called ‘1792’ (♀). The seed of ‘Fantasy Crystal Red’ was bought from Sakata Seed Ltd. ‘1792’ (non-patented in the United States) is a decumbent, wild type Petunia plant native to Brazil.

In April 1998, crossing ‘Fantasy Crystal Red’ as female parent and ‘1792’ as pollen parent was conducted at the Yokaichi-shi, Shiga. In January 1999, 120 seedlings were obtained from that crossing. These seedlings were grown in pots under glass and tested. One individual plant was selected in view of its decumbent growth habit and its flower color. That seedling was propagated by cutting from July 1999, and a trial by flower potting and bedding was carried out from April 2000, at the Yokaichi-shi, Shiga. The botanical characteristics of that plant were then examined, using similar varieties ‘Revolution Pinkvein’ (U.S. Plant Pat. No. 9,341) and ‘Revolution Marrose’ (U.S. Plant Pat. No. 10,904) for comparison. As a result, it was concluded that this petunia plant is distinguishable from any other variety whose existence is known to us, and is uniform and stable in its characteristics. The new variety of petunia plant was named ‘Sunbapive’.

In the following description, the color-coding is in accordance with the Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S. Color Chart).

The female parent used in the crossing of ‘Sunbapive’ called ‘Fantasy Crystal Red’ has an erect growth habit while that of the new variety is decumbent. The branching is fewer than the new variety. It has small single flowers, the petals having a vivid red (R.H.S. 52A) color with strong red (R.H.S. 53C) vein.
